Description
Die vorliegende Erfindung geht von einer Bedien- und/oder Anzeigeeinrichtung für elektrische Geräte, insbesondere in Kraftfahrzeugen aus, mit einem einen Kunststoffkörper umfassenden Teil der Einrichtung, dem ein mittels einer durch fokussierte, energiereiche Laserstrahlung hervorgerufenen, chemischen Materialumwandlung erzeugtes Piktogramm zugeordnet ist.The The present invention is based on an operating and / or display device for electrical equipment, in particular in motor vehicles, with a plastic body comprising Part of the facility, the one by means of a focused, high-energy Laser radiation induced, chemical material conversion generated Pictogram is assigned.
Derartige Einrichtungen sind z.B. in Kraftfahrzeugen dafür vorgesehen, um insbesondere elektrische Funktionsvorgänge mittels Piktogramm definiert einzuleiten bzw. Funktionssituationen durch solche Piktogramme zu verdeutlichen.such Devices are e.g. provided in motor vehicles, in particular electrical , operations defined by means of a pictogram or functional situations to clarify by such pictograms.
Ein dem Oberbegriff des vorliegenden Hauptanspruchs entsprechender Gegenstand ist z.B. aus dem in der Zeitschrift „Kunststoffe" (Ausgabe 11/1993, Carl Hanser Verlag, München) erschienen Aufsatz „Berührungslos Beschriften mit dem Laserstrahl" von U. Haack et al. bekannt. Dort werden Piktogramme auf der dem Bediener zugewandten Oberfläche eines aus Kunststoff bestehenden Teils der Bedien- und/oder Anzeigeeinrichtung durch fokussierte, energiereiche Laserstrahlung erzeugt. Der Farbkontrast auf der Oberfläche kann dabei durch verschiedene chemische Prozesse erzielt werden, wie z.B. die sog. Karbonisierung des Kunststoff-Grundmaterials oder den Farbumschlag eines im Kunststoff-Grundmaterial gelösten Farbstoffs.One The preamble of the present main claim corresponding subject is e.g. from the journal "Kunststoffe" (issue 11/1993, Carl Hanser Verlag, Munich) appeared essay "Contactless Labeling with the laser beam "from U. Haack et al. known. There are pictograms on the server facing surface a plastic part of the operating and / or display device generated by focused, high-energy laser radiation. The color contrast on the surface can be achieved by various chemical processes, such as e.g. the so-called carbonization of the plastic base material or the color change of a dissolved in the plastic base material dye.
Bei dieser Art der Piktogrammgestaltung ist jedoch nur eine zweidimensionale, auf die Oberfläche der Einrichtung beschränkte Darstellung realisierbar, die u.a. dadurch, daß bevorzugt opakes Kunststoffmaterial zum Einsatz kommt, auch bezüglich der Ausleuchtung nur sehr eingeschränkte Möglichkeiten bietet.at However, this type of pictogram design is just a two-dimensional, on the surface limited to the institution Representation feasible, the u.a. in that preferably opaque plastic material is used, also regarding the illumination offers only very limited possibilities.
Aus
der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Bedien- und/oder Anzeigeeinrichtung der eingangs erwähnten Art derart weiterzubilden, daß neuartige, insbesondere durch verschiedenste Ausleuchtungsvarianten beeinflußbare Gestaltungsmöglichkeiten der durch die Piktogramme verkörperten Symbolik eröffnet sind.Of the The present invention is based on the object of and / or display device of the type mentioned in such a way that novel, in particular by various illumination options influenceable design options the one represented by the pictograms Symbolism opened are.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Kunststoffkörper zumindest im sichtbaren Spektralbereich lichtdurchlässig und von einer für den Betrachter nicht einsehbaren Stelle her beleuchtbar ist, und wobei das Piktogramm im Inneren des Kunststoffkörpers mit Abstand zu dessen Oberflächen angeordnet ist.According to the invention Task solved by that the Plastic body translucent and at least in the visible spectral range from one for the viewer can not be seen, and wherein the icon in the interior of the plastic body at a distance from its surfaces is arranged.
Bei einer mit optisch transparenten Standardmaterialien realisierbaren Ausführungsform des erfindungsgemäßen Gegenstands ist das Piktogramm im Kunststoffkörper durch eine Karbonisierung des Kunststoff-Grundmaterials erzeugt.at a realizable with optically transparent standard materials embodiment the article of the invention is the pictogram in the plastic body by a carbonation produced the plastic base material.
Eine Auswahl der Darstellungsfarbe des Piktogramms ist möglich bei einer Ausführungsform, bei der das Piktogramm durch die Aktivierung eines im Kunststoff-Grundmaterial unsichtbar gelösten, photoaktivierbaren Farbstoffs erzeugt ist.A Selection of the display color of the pictogram is possible with an embodiment, at the the pictogram by activating one in the plastic base material invisible, photoactivatable dye is generated.
Ein nur bei Bestrahlung mit ultraviolettem Licht sichtbares Piktogramm ist dadurch realisierbar, daß das Piktogramm durch die Aktivierung eines im Kunststoff-Grundmaterial unsichtbar gelösten, photoaktivierbaren Fluoreszenzstoffs erzeugt ist.One visible only when irradiated with ultraviolet light is thereby realizable that the Pictogram by activating one in the plastic base material invisible, photoactivatable fluorescent substance is generated.
Eine weitere Ausleuchtungsvariante ist z.B. dadurch möglich, daß der das Piktogramm beinhaltende, lichtdurchlässige Kunststoffkörper auf seiner Rückseite zusätzlich eine Elektrolumineszenzschicht aufweist.A another illumination variant is e.g. possible by the fact that the pictogram containing, translucent Plastic body on his back additionally has an electroluminescent layer.
Durch eine kratzfeste Oberflächenvergütung zumindest der vom Bediener erfaßbaren Oberflächen des lichtdurchlässigen Kunststoffkörpers wird die gute Sichtbarkeit des Piktogramms, das durch seine Anordnung im Inneren ja schon gegen Beschädigung z.B. durch Abrieb und dgl. geschützt ist, dauerhaft gewährleistet.By a scratch-resistant surface finish at least the operator can detect surfaces the translucent Plastic body is the good visibility of the pictogram, due to its arrangement inside already against damage e.g. protected by abrasion and the like is permanently guaranteed.
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Gegenstandes sind in den Unteransprüchen angegeben und werden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.Further advantageous embodiments of the subject invention are in the dependent claims and are based on a shown in the drawing Embodiment explained in more detail.
